Freelance Full Stack Developer information

What is a freelance full stack developer?

A Freelance Full Stack Developer is a self-employed professional who builds both the front-end and back-end of websites or applications. They work with various technologies, including databases, servers, APIs, and client-side interfaces, to create fully functional digital products. Unlike full-time employees, freelancers work on a project basis for multiple clients, offering flexibility in workload and schedule. Their responsibilities often include coding, debugging, deployment, and sometimes design.

What types of projects and clients can freelance full stack developers typically expect to work with?

Freelance Full Stack Developers often engage with a diverse range of projects, including website and web application development, e-commerce platforms, mobile app backends, and API integrations. Clients can range from startups and small businesses to established companies and entrepreneurs seeking bespoke digital solutions. The variety in clients and project scopes allows developers to constantly expand their skills and work experience, but it also means adapting quickly to new industries and client expectations. Freelancers typically manage their own workflow, communicate directly with clients, and are responsible for project timelines, making this role ideal for self-motivated technology professionals.

What are the key skills and qualifications needed to thrive as a freelance full stack developer?

To thrive as a Freelance Full Stack Developer, you need a solid grasp of both front-end and back-end programming languages (such as JavaScript, HTML/CSS, Node.js, Python, or similar) and a strong portfolio showcasing completed projects. Familiarity with frameworks like React or Angular, version control systems like Git, cloud services, and sometimes relevant certifications (such as AWS Certified Developer) are highly valued. Excellent communication, problem-solving abilities, time management, and client relationship skills help set freelancers apart. These competencies are crucial for effectively delivering end-to-end solutions, managing multiple projects, and building a reliable client base.

Job description

About SAPSOL Technologies Inc.
SAPSOL Technologies Inc. is a global innovation leader operating at the intersection of SAP, AI, and Quantum Computing.

We develop SR&ED-compliant, future-ready products such as TraceSecure.ai, HireRig.ai, and RoboCart.ai, combining automation, analytics, and intelligence into one powerful enterprise ecosystem.
Our mission is to drive the next generation of digital transformation using AI-driven, cloud-native, and quantum-enabled technologies.

Role Overview
We're hiring a deadline-driven Full-Stack Developer to work onsite in Mississauga on next-generation AI and SAP-integrated platforms.

You'll design, build, and deploy AI-enabled enterprise systems using our internal tech stack - Laravel MVC, Java, JavaScript, Progress Database, Docker, and Kubernetes - while maintaining full SR&ED compliance and delivering under tight timelines.

Key Responsibilities

  • Build and enhance modules for TraceSecure.ai, HireRig.ai, and Quantum-ready prototypes.
  • Integrate AI frameworks (OpenAI, Anthropic, LangChain, Gemini, etc.) into live systems.
  • Develop and maintain services using Laravel MVC, Java, and JavaScript (Node/Vue/React).
  • Manage and optimize Progress Database for speed and scalability.
  • Deploy solutions through Docker containers and Kubernetes orchestration.
  • Document all R&D activity for SR&ED compliance (uncertainties, experiments, results).
  • Consistently meet strict project deadlines with production-ready deliverables.
  • Collaborate with cross-functional teams, including AI and SAP consultants.

Required Skills

  • Expert in Laravel MVC
  • Proficient in Java and JavaScript (Node.js / Vue.js / React)
  • Experience with Progress Database or equivalent RDBMS
  • Strong knowledge of Docker & Kubernetes
  • Integration of AI APIs (OpenAI, Gemini, LangChain, etc.)
  • Understanding of RESTful APIs, CI/CD, and microservice architecture
  • Proven record of on-time delivery under demanding schedules
  • Familiarity with SR&ED documentation requirements

Preferred / Asset Skills

  • Any SAP knowledge is a strong asset (BTP, S/4HANA, Fiori, integration experience)
  • AI-driven microservices and vector databases (Pinecone, Weaviate, etc.)
  • Exposure to Quantum frameworks (Qiskit, Pennylane, D-Wave QUBO)
  • DevOps automation (Terraform, Helm, Jenkins)
